for Environmental
Permit no. EP-122/2002/D. The EM&A report is prepared by the
Environmental Team (ET) employed under Contract
No. HK/2011/07 –Wan Chai Development
Phase II and Central Wanchai Bypass – Sampling, Field Measurement and Testing
Works (Stage 2). This report presents the
environmental monitoring findings and information recorded during the
period of June 2015.
The cut-off
date of reporting is the last dayof each reporting month.

In
the reporting month, the principal work activities of the contract are
included as follows:

No action or limit level exceedances was recorded at ACL3 – City
Hall in the reporting month.

Due
to safety concern, the location of the continuous noise monitoring station
at City Hall was finely adjusted to the roof of the City Hall, Low Block
on 1 May 2013.

Air Quality
Monitoring

1-hour and 24-hour Total Suspended Particulates (TSP) monitoring
were conducted on every six days basis at ACL1 – City Hall and ACL2a –
Contractor HK/2012/08 Site Office.

No
action or limit level exceedances was recorded at ACL 1 – City Hall and
ACL2a –Contractor HK/2012/08 Site Office in the reporting month.

Due
to interruption of electricity supply, the 24hr TSP at ACL2a - Contractor
HK/2012/08 Site Office was rescheduled from 8, 18 and 29 June 2015 to 9, 19
and 30 June 2015 respectively.

Due to the defective electricity supply found
at monitoring station ACL1 and the advice from City Hall Building
Management, the air monitoring station ACL1 – City Hall was finely
adjusted on 28 Feb 2014 to an alternate electricity supply.

Due
to the large scale renovation works at People’s Liberation Army
Headquarter, a Proposal for Relocation of Air Quality Monitoring Station
at People’s Liberation Army Headquarter (ACL2) was formally submitted to
EPD on 4th November, 2013.

The
Proposal for Relocation of Air Quality Monitoring Station at People’s
Liberation Army Headquarter (ACL2) was approved by EPD on 27 November
2013.

According
to the approved proposal for relocation of Air Quality Monitoring station,
the action and limit levels of ACL2a shall adopt the reference monitoring
result from the baseline air monitoring report for EP/364/2009 in 22 April
2010 in which approved by EPD.

The
air quality monitoring at ACL2a – Contractor HK/2012/08 Site Office was
commenced on 7 December 2013.

6.

6.3.

6.5.1There was
no non-compliance from the site audits in the reporting period. The
observations and recommendations made in each individual site audit session
were presented in Section 8.

7.0.2.According
to the Final EM&A report of Central Reclamation Phase III (CRIII) for
Contract HK 12/02, the major construction activities were completed by end of
January 2014 and no construction activities were undertaken thereafter and the
water quality monitoring was completed in October 2011.As such, it is considered that there were no
cumulative construction impact due to the concurrent activities of the current
projects with the Central Reclamation Phase III (CRIII) undertaken by
contractor HK12/02 in the reporting month.

7.0.3.According to the
construction programme of Central-Wanchai Bypass at Wanchai West at the Central
Reclamation Phase III area, removal of L-shape wall, installation of caisson
seawall and ELS works were performed in June 2015 reporting month. As no project
related exceedance were recorded during the reporting period, cumulative
construction impact due to the concurrent activities of the current projects
with the Central Reclamation Phase III (CRIII) was considered as insignificant.

7.0.4.According to the construction programme of Wan Chai Development Phase
II, Central-Wan Chai Bypass and Island Eastern Corridor Link projects, the
major construction activities under Wan Chai Development Phase II were
tunnel works and ELS works at Wan Chai East and temporary reclamation, D-wall
construction and ELS works at Wan Chai West. The major construction
activities under Central-Wan Chai Bypass and Island Eastern Corridor Link
Projects were bridge construction and road works at Central Interchange, land
based bored pilling works and ELS works at Victoria Park, D- wall construction
and ELS at TS3, IEC demolition and tunnel works at North Point area in the
reporting month.

7.0.5.No significant air impact from construction activities was anticipated
in the reporting month. Besides, no project related exceedance was recorded
during the water, air and noise environmental monitoring events in the
reporting month. Thus, it is evaluated that the cumulative construction impact
from the concurrent projects including Central Reclamation Phase III (CRIII),
Wan Chai Development Phase II (WDII), Central-WanChai Bypass (CWB), Island
Eastern Corridor Link projects (IECL) was insignificant.
